American city Detroit files bankruptcy

Detroit files for bankruptcy protection

City losing residents as tax base shrinks

By The Associated Press

Once the very symbol of American industrial might, Detroit became the biggest U.S. city to file for bankruptcy Thursday, its finances ravaged and its neighbourhoods hollowed out by a long, slow decline in population and auto manufacturing.

The filing, which had been feared for months, put the city on an uncertain course that could mean laying off municipal employees, selling off assets, raising fees and scaling back basic services such as trash collection and snow plowing, which have already been slashed.

“Only one feasible path offers a way out,” Gov. Rick Snyder said in a letter approving the move.

71pc households in Sindh food insecure: report

BY HASAN MANSOOR

KARACHI: Despite having 14 million acres under crop cultivation in Sindh, over 71 per cent households in the province are food insecure — the highest level of food insecurity among the provinces and region, it emerged on Sunday.

Of these food insecure households, 34pc are food insecure with moderate hunger and 17pc are food insecure with severe hunger, according to a report drafted by the provincial planning and development department.

The department prepared the draft in January ‘for discussion’ by its own research assisted with several reports of the World Bank, London School of Economics, World Health Organization, Unicef, Lancet, Pakistan Social and Living Standards Measurement, Save the Children, SDPI, SDC, World Food Programme and several independent researchers.

Between 2003-04 and 2008-09, the number of surplus food producing districts decreased from 11 to six while the number of food deficit districts increased, the report said.

Eight of Sindh’s 23 districts, most of them in the southern part of the province and in its coastal belt were identified as having ‘extremely poor’ conditions for access to food.

Scientists Discover Quadruple Helix: Four Strand DNA In Human Cells

by Arjun

The human race knows very little of itself, almost like a race with amnesia. As we continue to move forward through time, new discoveries are made that make old theories obsolete and false. It’s a good lesson that shows us how we can attach ourselves to “truths” and believe them whole-heartedly, often forgetting that truth is constantly changing and new paradigms of perception always lurk around the corner.

Decades after scientists described our “chemical code” of life using the double helix DNA, researchers have discovered four-stranded DNA within human cells. The structures are called G-quadruplexes, because they form in regions of DNA that are full of guanine, one of the DNA molecule’s four building blocks. The others are adenine, cytosine and thymine. A hydrogen bond is responsible for holding the four guanines together. The four stranded DNA usually presents itself right before cell division.

The discovery was published online in Nature Chemistry, and you can take a look at it here. The study was led by Shankar Balasubramanian at the University of cambridge, UK.

For us, it strongly supports a new paradigm to be investigated – using these four-stranded structures as targets for personalized treatments in the future.We have found that by trapping the quadruplex DNA with synthetic molecules we can sequester and stabilise them, providing important insights into how we might grind cell division to a halt — Shankar Balasubramanian

The study went on to show certain links between concentrations of four-stranded G-quandruplexes and the process of DNA replication, which is crucial to cell division and cell production. G-quadruplexes, (when targeted with synthetic molecules responsible for trapping and holding these DNA structures) prevent cells from replicating their DNA, thus blocking cell division. Scientists believe that this discovery could possibly lead to a stop in cell proliferation at the root of cancer ….
